Texas, Lavaca County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas

Lavaca County Building and Safety Divisions and Jurisdiction

Lavaca County does not have a general building department or a city-style general building permit program for unincorporated areas. The county's permit authority is limited to specific areas such as floodplain development, On-Site Sewage Facilities (OSSF), subdivision platting, and certain road, driveway, pipeline, waterline, and oil and gas permits. The Flood Plain Management Administration and the OSSF inspector/designated representative are the primary points of contact for these permits. For general construction in unincorporated areas, there is no verified countywide building code adoption; instead, the county has adopted a flood damage prevention ordinance and an OSSF regulatory program.

Rules for Properties in Unincorporated Areas

For properties in unincorporated Lavaca County, a Development Permit is required before starting any construction. This permit involves a floodplain determination. If the property is within a Special Flood Hazard Area, a specific floodplain development permit and supporting documentation are necessary.

On-Site Sewage Facility (OSSF) permits are mandatory for the installation, replacement, or repair of septic systems. These applications must be submitted by a TCEQ-licensed OSSF installer. An Approval to Construct will be issued within 30 days of application submission, and no OSSF construction can begin before receiving this approval.

Subdivision of land outside municipal limits that creates two or more lots requires a subdivision application and surveyed plat. Lavaca County will determine if any exemptions apply. No lots or tracts can be sold until approved by Lavaca County.

Additionally, permits are required for specific activities such as installing access driveways on county road right-of-ways, pipelines, and temporary or renewal waterlines.

While there is no countywide general building code for unincorporated areas, Texas law (specifically Subchapter F of Local Government Code Chapter 233) authorizes counties to adopt the International Residential Code (IRC) for construction in unincorporated areas. However, it is not explicitly stated if Lavaca County has adopted the IRC for general construction.

Plumbing work performed by licensed plumbers in Texas, even in unincorporated areas, must adhere to plumbing codes adopted by the Texas Board of Plumbing Examiners.

Texas Plumbing Legislation, Codes, and Guidelines

State Statutes and Codes

Plumbing regulation in Texas is primarily governed by the Plumbing License Law, which is codified under Chapter 1301 of the Texas Occupations Code. This statute mandates that plumbing work be performed by or under the direct supervision of a licensed plumber, with specific exceptions for homestead owners. Regarding technical standards, the Texas State Board of Plumbing Examiners (TSBPE) adopts plumbing codes to ensure the proper design, installation, and maintenance of plumbing systems. While the state adopts specific codes as a baseline, Texas law allows municipalities and political subdivisions to adopt and amend plumbing codes to address local concerns, provided those amendments do not substantially vary from state rules or laws. Consequently, local jurisdictions may choose between recognized standards, such as the International Plumbing Code (IPC) or the Uniform Plumbing Code (UPC), and apply their own local amendments.

Primary State Board

The Texas State Board of Plumbing Examiners (TSBPE) is the primary state agency responsible for the regulation of the plumbing industry in Texas. Its authority includes the licensing and examination of plumbing professionals, the enforcement of the Plumbing License Law, the adoption of plumbing codes for areas not otherwise regulated, and the oversight of continuing professional education for licensees.
